This article is about exercise for healthy aging and a young brain. A review article in Medical News Today states that several research papers showed that exercise greatly improves brain health, cognition and mood. It also reduces the risk of neurodegenerative diseases.

The benefits of regular exercise 

Here is a list of the beneficial effects of regular exercise:

  • Increased muscle strength
  • Improved heart health
  • Lower blood sugar
  • Improved mood
  • Alleviates stress
  • Improvement of cognitive function

Researchers from Stanford Medicine have examined in a rat model how exactly exercise influences various tissues. Unfortunately, such experiments in humans are not possible and results of rat experiments do not readily translate into the human context. In 8 weeks of regular exercise rats experienced stimulation of the immune system, a reduction of the stress response, an increase of energy production and stimulation of the metabolism. From indirect measurements we know that in humans the same findings likely also hold true. The mitochondria, the area in cells where energy production occurs, are stimulated in muscles, the heart, liver, kidneys, and white adipose tissue.

Effect of exercise on the immune system

Researchers showed in a mouse model that exercise stimulated the T cell response and rejuvenated aging microglia in the brain. The result is a strengthening of the immune system and rejuvenation of the supportive microglia. In the aging human regular exercise rejuvenates microglia in the hippocampus. This can prevent dementia and Alzheimer’s disease.

Exercise strengthens brain cell connections

How does exercise affect the functioning of the brain?

Ryan Glatt is a senior brain health coach and director of the FitBrain Program at Pacific Neuroscience Institute in Santa Monica. He said: “Exercise enhances synaptic plasticity and blood flow while reducing inflammation and increasing the expression of neurotrophic factors like Brain-derived neurotrophic factor (BDNF). These effects can synergistically improve memory, learning, and overall brain health.”

The best forms of exercise for brain health

Glatt said: “Activities combining physical and cognitive challenges, like dance or tai chi, can be especially effective for certain aspects of brain health.”

Brisk walking is a simple method of exercise. However, we also need isometric exercises, which helps muscle strength and endurance. A good way of combining the two forms of exercise is to regularly go to a gym. Use a treadmill for 30 minutes and then use 30 minutes of a workout with 10 weight machines. Mix this with tai chi or ballroom dancing several days per week. This keeps you mentally and physically fit.

Slow your biological age through the use of the “Essential 8”

Research identified 8 factors that determine how long you live. These 8 factors are what can lower your biological age by 6 years. Here are the 8 factors:

  • Diet

    A diet high in fruit, vegetables and lean meats helps you to lower your cholesterol level. In addition, avoid trans fats, fried foods and sugary foods. This helps you to lose weight and prevents Together with regular exercise eating a healthy diet prevents heart attacks and strokes.

  • Activity

    The American Heart Association recommends 150 minutes of moderate-intensity aerobic activity per week. Alternatively, 75 minutes of vigorous aerobic activity achieve the same thing. Examples of moderate aerobic activity are a brisk walk, jogging, biking, social dancing and water aerobics. Vigorous aerobic activity involves spinning, running, swimming laps or jumping rope. Exercise reduces blood pressure, blood sugar, and cholesterol. It also helps people to reduce weight.

  • Quit smoking

    Smoking cigarettes, vaping or using e-cigarettes causes your  body to develop higher blood pressure and damages your blood vessels because of circulating toxins. You also develop shortness of breath from narrowed airways. On the other hand, when people quit smoking, their risk of coronary heart disease drops to half after 1 year.   

  • Getting enough sleep

    People who don’t get enough sleep at night tend to have higher blood pressures, higher cholesterol and higher blood sugar values. This leads to weight increase and obesity. Sleeping at night for 7 to 9 hours improves cardiovascular health.

  • Body mass index (BMI) 

    An elevation of your body weight occurs when you eat the wrong foods and combine this with a sedentary lifestyle. Increased weight causes heart and joint problems as well as diabetes. Eating the right foods and exercising regularly gets your BMI into the normal range. This reduces your biological age.

  • Cholesterol

    An increase of cholesterol can cause heart attacks and strokes. But when you watch your fat and cholesterol intake you can reduce your cholesterol level. Make healthier choices with foods like reducing saturated fats, reducing refined carbohydrate intake, eating more vegetables and leaner meats. This reduces inflammation in the arteries and plaque deposits with much lower risks of heart attacks and strokes.

  • Blood sugar

    Increased blood sugars lead to diabetes. In this case there is accelerated hardening of the arteries in the heart, brain, eyes, and kidneys. This leads to premature heart attacks and strokes. People need to avoid eating refined sugars, carbohydrates (bread, pasta, rice) and sugary drinks. This normalizes blood sugars and your biological age reduces. Regular exercise is also important to burn off any excess sugar in the system.

  • High blood pressure

    An elevated blood pressure strains the arteries and the heart. If you don’t pay attention to this you are at a high risk of getting heart failure, a heart attack or a stroke. Sticking to a heart healthy diet, avoiding salty foods, and exercising regularly allows you to lower your blood pressure and avoid the above mentioned complications. If these measures alone do not reduce your blood pressure to normal, ask your doctor to prescribe blood pressure lowering medications for you.

  • Bioidentical hormone replacement

    What was not contained in the 8 factors was bioidentical hormone replacement. As you can see from the illustration, testosterone in males reduces more slowly in males (with a delay of 10 years) in comparison to estrogen reduction in menopausal women. Several authors describe that men and women in andropause and menopause live longer when bioidentical hormones are administered compared to those that do not use hormone replacement therapy.

Conclusion

Regular exercise even in older age keeps your brain free from dementia or Alzheimer’s disease. But in addition to this other research showed that 7 more factors are important to reduce your biological age. They are a healthy diet, quitting smoking, getting enough sleep and reducing your body mass index. In addition, you need to keep your cholesterol and blood sugar levels normal. Control high blood pressure with a healthy diet, refrain from salty foods and if necessary, treat it with medication.

Life’s essential 8 factors

It is important to simultaneously control all these “Life’s essential 8” factors for optimal control. People who do this were found to consistently have a lower biological age than others who do not. They also tend to not get Alzheimer’s disease whereas controls do. Lifestyle factors matter for healthy aging and a young brain. Studies showed that the biological age of those who take care of their lifestyles is on average 6 years younger than that of controls. You can reduce your biological age even further with bioidentical hormone replacement in andropause and menopause.

Eating the right Food Determines your Health

By | Cancer, diet, exercise, food, Health, heart attack, Mortality, Nutrition, Prevention, sleep, sugar

CNN had an interview with Dr. Leana Wen about the fact that eating the right food determines your health. Dr. Wen is a wellness expert, an emergency physician and adjunct associate professor at George Washington University.

How much does the quality of food we eat influence our health?

There are detailed studies that showed the following effects of healthy food on our lives.

  • If you eat a diet consisting of more vegetables, fruits, whole grains and nuts, the following will happen. You could exceed the age of controls eating unhealthy food by 10 to 13 years.

Specifically, a woman starting such a diet at age 20 would add 10 years to her life, when starting at age 60 she could add 8 years to her life. For men starting this diet at age 20 would allow him to gain 13 years, when starting at age 60 he would add 9 years to his life.

Additional healthy food studies

  • A 2023 Nature study found that men can add 10.8 years, women 10.4 years by switching their diets. This switch was from unhealthy diets to a longevity diet with more whole grains. In addition, the healthy diet contained more nuts and fruits and less sugar-sweetened beverages and processed meats.
  • Another 2023 study from the Jama network followed over 100,000 people for more than 30 years. There was an association between adopting healthy eating patterns and a reduction in early mortality. People on a healthy diet reduced their risk of early death by 20%! The study also noticed that people who ate more whole grains, fruits, vegetables, nuts and legumes had fewer other diseases. They were less likely to die from cancer, cardiovascular illness and respiratory and neurodegenerative disease. These were important findings. 

What kinds of food make you live longer?

Dr. Wen stated clearly that it is only minimally processed, whole food that allows a person to live longer. The highly processed foods like processed meats, sausages, cakes and cookies are a “no go”. They are the ones that cost lives from heart attacks, strokes and cancer. On the other hand, leafy green vegetables, fresh fruits and whole grains associate with significantly reduced mortality. Fish contains omega-3 fatty acids, which reduce heart disease and dementia. It is also a good source of protein. So, stay away from hot dogs and chicken nuggets, instead enjoy salmon fillet or roasted chicken.

Foods that you need less of

Avoid sugar sweetened sodas and energy drinks, as they elevate cholesterol levels and cause heart attacks. Next, stay away from ultra-processed foods like chips and candies. In one study with more than 11,000 participants people who ate a lot of ultra-processed foods had a 31% higher risk of mortality.

With what do you replace junk food?

Here are a couple of examples. Somebody who used to drink a lot of sodas can replace them with water, sparkling water, flavored water or lemon juice, sweetened with stevia. Instead of snacking on ultraprocessed foods like chips, candies or pretzels eat nuts instead. Look at the list of ingredients before you buy anything in the grocery store. If there is a long list of ingredients including chemicals, this is ultraprocessed food. Replace it with minimally processed foods with only a few items on the ingredient list.

Other advice for health and longevity

  1. If possible, eat three meals a day (breakfast, lunch and dinner). Stop eating 2 hours before bedtime to allow your guts to digest the food you previously ate. This avoids heart burn and interference with your sleep.
  2. Exercise regularly. Studies showed that 150 minutes of vigorous exercise per week reduced mortality by 23%.
  3. Take care of stress in your life. Cherish your social life and socialize; it is important for longevity. See your doctor regularly to take care of any medical problems you may have.
  4. Watch your sleep habits. Many studies have shown that adults need 7 to 8 hours of sleep. Sleep restores your hormone glands, gets them ready for the next day, but it is also important for longevity.
  5. Keep your body mass index (BMI) between 21.0 and 24.0. Personally, I keep my BMI between 21.0 and 22.0. Any extra pounds of fat merely lead to elevated cholesterol and triglycerides. Eventually this leads to heart attacks and strokes, but also to diabetes.
Eating the right Food Determines your Health

Eating the right Food Determines your Health

Conclusion

A recent article in CNN described that eating the right food determines your health. One study said that you should eat a diet consisting of more vegetables, fruits, whole grains and nuts. Doing this increases your life expectation by 10 to 13 years compared to controls who ate unhealthy food. It is only minimally processed, whole food that allows a person to live longer. You must eliminate ultraprocessed food. This means you should not consume sausages, fries, chips, pretzels and other overprocessed foods. Instead, eat leafy green vegetables, fresh fruits and whole grains that associate with significantly reduced mortality. Yes, eating the right food determines your health.

Backup your New Year’s Resolutions by looking at short-term Consequences

By | alcohol, Anxiety, Cancer, Cardiovascular disease, Diabetes, exercise, fasting mimicking diet, Health, heart attack, Insomnia, Smoking, sugar

In the New Year it pays to backup your New Year’s resolutions by looking at short-term consequences. An article in “the conversation” explains how you can keep yourself motivated to stick to healthy habits. The alternative would be to fall back into unhealthy habits, which lead to various disease conditions. Traditional thinking centered around keeping long-term outlooks in front of your mind when tempted by the smell of doughnuts. In these cases, you think that the long-term consequences of eating doughnuts or consuming sugary drinks result in diabetes and obesity. But the smell or taste of unhealthy foods can be so overpowering that the long-term consequences of potential diseases is forgotten. This is the point when your New Years resolution may fade away in favor of falling back to unhealthy eating habits.

Think short-term to resist temptation

The new approach is to replace the thinking of long-term outlooks by short-term outlooks. The authors cited an example of 4000 participants in 7 separate studies. When the short-term consequences of anxiety and a sugar and caffeine crash were explained for caffeine containing sugary drinks, 25% of participants were able to abstain from the energy drinks in comparison to those who were informed about long-term consequences.

Another experiment

A similar experiment involved the consumption of sugar in the form of cookies. One group of participants read about the short-term effects of eating sugar. A second group read about the long-term effects of eating sugar. A third group did not get any information about the effect of sugar. There was also a “reward system” for all the participants: they had to decide between receiving a tote bag or eating cookies. Those who had read about the short-term effects of sugar were 30% less likely to choose cookies than the ones who read about the long-term effects. The ones who read the short-term effects were 45% less likely to choose the cookies than the ones who read nothing about the effects of sugar.

Verbalizing short-term consequences

Here are some thoughts that help to verbalize short-term consequences:

  • For alcohol: excessive drinking can lead to poor sleep and hangovers.
  • Fast food can make you feel bloated or give you indigestion.
  • Sugar and starchy meals: make you bloated and give you an acidy stomach, also will lead to rapid weight gain.
  • Focus on the good taste of apples and carrots. People will eat more of it and get the health benefits without mentioning it.

You can keep your goals easier when you combine them with small rewards here and there. When you have achieved one thing, you could watch your favorite TV show. Another reward could be a brief visit to the gym that makes you feel more fit. Or go and buy yourself a new pair of shorts for the gym. The authors of this article provide evidence from studies that showed that several mini rewards distributed throughout the day are more effective than big rewards at the end of the day.

Measurements of weight fluctuations

I found that body composition scales are very useful to monitor your diet intake. Here is an example how I use this device. My weights, fat% and body mass index for a number of days is listed below. The first line shows the baseline measured in the morning. On Saturday lunchtime I was invited to a Christmas family dinner. I ate more than I should have had. You can see the results on the Sunday readings: weight up, fat up and BMI up. I watched my calorie intake throughout Sunday.

Weekday              Weight (KG)                 Fat %        Body mass index

Saturday:                   63.6                           13.2                  21.7

Sunday:                     64.0                           14.2                  21.9

Monday:                    63.4                           14.3                  21.7

It took another two days (Wednesday) before the fat percentage was down to 12.9.

There is another powerful tool, Dr. Valter Longo’s fasting mimicking diet. I reported about this under this link. Briefly, once a month I eat only 500 to 600 calories daily for 5 days. This helps me to lose my body mass index from 21.8 down to 21.1 or 21.2. After that I can eat a normal diet until the next month when I do the fasting mimicking diet again. It is an easy way to keep my body mass index in the 21.0 to 22.0 range. My wife and I prepare our own 500 to 600 calorie diet with natural food.(No, you do not get much, but it can taste good!) We do not buy Dr. Longo’s expensive diet boxes.

Backup your New Year’s Resolutions by looking at short-term Consequences

Backup your New Year’s Resolutions by looking at short-term Consequences

Conclusion

Focusing on short-term goals and consequences increases the percentage of success for those who have New Year’s resolutions. You can use this for many different approaches: eating less sugar, losing weight, getting regular exercise, reducing your alcohol intake, cutting out fast food and increasing your healthy vegetable and fruit intake. I also added a description of what I do with the help of body composition scales to control my weight and body mass index. I also use Dr. Longo’s fasting mimicking diet once per month for 5-days. Since December 2017 (for 6 years) I practiced this. I find it extremely useful to maintain my body mass index in the 21.0 to 22.0 range. Medicine knows that it is important to keep your body mass index below 25.0. This will prevent heart disease, type 2 diabetes and cancer. It also helps to look forward to a healthy New Year.

Any Form of Exercise is good

By | Cancer, Cardiovascular disease, diet, exercise, Fitness, Health, heart attack, Mortality

Here are a few items that can prolong life; among them any form of exercise is good. This article concentrates on the exercise part in relation to longevity. A recent publication described how regular exercise prolongs your long-term survival. According to a study released on occasion of the American Heart Association’s Scientific Session 2023 there are 8 major factors that prolong life: healthy diet, physical activity, nicotine exposure, sleep health, BMI, cholesterol, blood sugar, and blood pressure.  Among this group of factors regular physical activity plays a major role to prolong your life. Researcher who studied various people found that those who neglected their physical health had a chronological age of 53, but their average biological age was 57. On the other hand, a group of fit people who engaged in regular physical exercise had a chronological age of 41 years, but a biological age of 36.

Clinical trials showing that any form of exercise is good

JAMA Internal Medicine study by Dr. del Pozo Cruz 

This study examined what the optimal amount of physical activity per week is to reduce mortality compared to an inactive population. 500,705 eligible US adults were observed for about 10 years. The abbreviations that the authors used in the study were as follows:

MPA: moderate aerobic physical activity

VPA: vigorous aerobic physical activity

MSA: muscle-strengthening activity

Results of mortality reduction with various amounts of physical activity

  • The best group engaged in more than 0 to 75 minutes of MPA combined with more than 150 minutes of VPA and 2 or more MSA sessions per week. Their mortality rate was 50% lower than an inactive comparison group.
  • The optimal combination for reduction of cardiovascular disease (CVD) and cancer mortality risk was as follows: more than 150 to 225 minutes of MPA, more than 0 to 75 minutes of VPA, and 2 or more MSA sessions per week. This reduced combined mortality of CVD and cancer by 70%.
  • The researchers stated that the adjusted mortality rates represented 50% lower mortality rate for all-cause and cancer mortality. The mortality rate for CVD mortality was 3-fold lower than for inactive controls.

Smallest amount of exercise that reduces mortality

In a study published in the European Heart Journal the authors asked how little exercise per week was enough to reduce mortality from heart disease. They found that it takes at least 15–20 min/week of vigorous physical activity (VPA) to reduce mortality from heart attacks by 16–40%. If you increased the exercise level by 50–57 min/week the mortality rates reduced even further.

Are physically active jobs healthy?

Recent research showed that people who work in physically demanding jobs are more likely to develop early cognitive impairment. This is the pre-stage of Alzheimer’s disease. 15.5 % of people who worked in high levels of occupational physical activity developed dementia. This compared to 9% risk for people whose work involved a low level of physical activity, not too much and not too little. The finding confirms the notion that there is a need for balance of physical exercise. Several publications stressed what is optimal in terms of exercise: vigorous (75 to 300 minutes per week) and moderate physical activity (150 to 600 minutes per week). People who expose themselves to these amounts of exercise live the longest and stay healthy.

Discussion

The studies discussed here showed that the right amount of exercise can reduce mortality from heart disease and cancer. However, exercise is not the only factor that can do this. It is important to combine regular exercise with a healthy diet. Your diet should consist of fruits and vegetables, whole grains, low-fat dairy products, lean proteins and limit saturated and trans-fat, added sugars, and sodium. In addition, you need enough sleep, maintain a healthy weight, manage your stress, and don’t smoke.

Any Form of Exercise is good

Any Form of Exercise is good

Conclusion

In this review I touched on the importance of regular exercise to reduce mortality from heart disease and cancer. Vigorous (75 to 300 minutes per week) and moderate physical activity (150 to 600 minutes per week) reduce mortality from heart attacks by 16% to 40%. But physical exercise is only one factor of mortality reduction. If you want the full benefit from other factors, you must quit smoking, eat a Mediterranean type diet with fruits and vegetables, whole grains, low-fat dairy products and lean proteins. Also you should limit saturated and trans-fat, added sugars, and sodium. In addition, you need enough sleep, maintain a healthy weight and manage your stress. Once you adopted this lifestyle, you live longer and you will get less diseases.

Learn about Longevity from the Blue Zones

By | diet, Fitness, Health, lifestyle, Mortality, Nutrition, Processed food, red meat, sleep

People who live in blue zones often turn 100 or older, so we can learn about longevity from the blue zones. The 5 most often cited blue zones are in Okinawa, Japan; Sardinia, Italy; Nicoya, Costa Rica; Icaria, Greece; and Loma Linda, California, United States. But there are many more blue zones throughout the world. These zones contain the most centenarians, people who have reached the age of 100. It is thought that it is the people’s lifestyle that makes them live much longer than the rest of the world.

Lifestyle of centenarians

People are active, are bicycling, walking, swimming, constantly on the go and they are careful about what they eat. They stay slim, but are muscular. Their diet consists mostly of vegetables and salads, with very little meat. They may consume a small piece of beef on Sundays, but not during the rest of the week. Fish may be a part of their diet two or three times per week.

Diet characteristic of blue zones

Sandee LaMotte  published an article on March 4, 2023 at CNN, which describes the diet consumed in blue zones. People in blue zones are active, handle stress well, are close to friends, have a purpose in life and are often members of a social or religious group. They eat mostly a plant-based diet and they stop eating before they are full.

The food consists of complex carbohydrates. No processed foods are eaten. The American Heart Association says: “Complex carbohydrates, such as beans, peas, vegetables and whole grains provide vitamins, minerals and fiber that can go missing in processed and refined foods. In addition, they are digested more slowly, and the fiber helps you feel full longer.”

Origin of blue zone foods

The blue zone food has its roots in the African, Asian, Latino and Native American diets. Dan Buettner originally published an article about the blue zones in the National Geographic Magazine. Recently he published a collection of 100 blue zone recipes in book form.

The Mediterranean diet is very close to blue zone eating.

What blue zone meals contain

Buettner said: “The five pillars of every longevity diet, including the blue zone, are whole grains, vegetables in season, tubers, nuts and beans. In fact, I argue the cornerstone of a longevity diet is beans.” People in blue zones eat similar foods as those who eat a Mediterranean diet, but they do not eat as much fish as people on a Mediterranean diet. People on a blue zone diet don’t eat any milk products. On the other hand, goat and sheep’s milk cheeses such as feta and pecorino are part of the blue zone diet. In the blue zones the consumption of purple sweet potatoes, sesame seeds, fresh vegetables and fruit are the major staples.

More info about Blue Zone diet

All of the meals contain complex carbohydrates, micronutrients and a whole variety of fiber.

Perhaps the important difference to the Standard American diet is that in the blue zone there is a lack of beef, hamburgers, processed foods and highly processed carbohydrates like bread, pasta, sugar-sweetened beverages, salty snacks like potato chips, candies, cookies and processed meats (bacon, sausages or cold-cuts). People in blue zones eat very little bread and if they do, they eat sourdough bread, which does not raise the blood sugar level as the highly refined white bread.

Recapturing healthy foods

So, what foods are blue zone people really eating? Tofu, quinoa, mushrooms, lentils, beans, turnip greens, artichokes, asparagus, chickpeas and spinach are the main staples of their nutrition. They stay away from sugar, rarely eat meat (once or twice per week) and otherwise have a healthy lifestyle. Scientists think that longevity comes from the healthy lifestyle and diet, which centenarians practice. Several longevity genes get activated as explained in this publication. This translates into living long lives with very few illnesses and experiencing energy until the end of their lives.

Conclusion

We can learn a lot from observing what centenarians eat and do. Scientist have investigated the lifestyle of people living in blue zones in various parts of the world. These zones contain the most centenarians, people who have reached the age of 100. People in blue zones eat mostly vegetables and very little red meat. They avoid sugar and processed foods. But they are also very active, have a rich social life and allow themselves enough sleep. Scientists accumulated evidence that genetic longevity switches are activated by the life style of people living in blue zones.  It is the activation of these epigenetic switches that are responsible for the longevity of people in blue zones.

Plant-Based Meat Alternatives are Healthier

By | Cancer, Cardiovascular disease, diet, food, Health, Nutrition, Obesity, Weight loss

A recent study showed that plant-based meat alternatives are healthier than the original meat dishes. This spread into various health websites on the Internet. One example is this one.

Some statistics about plant-based meat alternatives

Plant-based meat alternatives came to the market in the 1960’s. At that time, they consisted mainly of soy. Later textured vegetable protein joined soy products. Today they consist of pea protein, soy, potato, oils, various binders and flavorings to mimic the texture and flavor of meat.

The global plant-based meat market was about 5 billion USD last year. It is projected to increase by 19% from 2022 to 2030. The plant-based dairy alternatives market totaled 11 billion in 2020. The estimate is that this will grow to 32 billion in 2031.

How healthy are plant-based substitutes?

In the center of this discussion is the publication of Christopher J. Bryant from the Bath University in England. This publication reviewed 43 studies regarding plant-based substitutes regarding healthiness and environmental sustainability. In the following I am discussing the findings, particularly about health benefit of plant-based foods versus meat-based foods.

Problems with our current food consumption

There are several problems with human diseases that are transmitted from wildlife. HIV arouse from hunting of non-human primates. Rabies was transmitted in South America by vampire bats from cattle to humans. Early cases of severe acute respiratory syndrome (SARS) came from contact with wild life. Finally, bats transmitted the SARS coronavirus-like virus from wild animals and live animal markets to humans. Subsequently human to human transmission caused the spread of Covid all around the world as a pandemic.

Use of antibiotics in feedlots

In order to control diseases in closely kept animal feedlots farmers feed the livestock antibiotics. This helps to contain infections, but it also poses a grave problem to humans as antibiotics become more and more resistant. Superbugs developed this way. 18% of meat imported from China was contaminated with Salmonella. 88% of those exposed to contaminated meat were resistant to at least one antibiotic. But 58% were resistant to multiple antibiotics.

A Harvard study from Boston showed in 2020 that red meat and processed red meat consumption caused 15% more heart attacks compared to those who substituted the protein source with plant-based foods. The same study also noted that the heart attack rates were about 15% less for subjects who substituted meat with plant products in comparison to meat eaters. 

Other results of the study

Several of the reviewed studies compared the nutritional profile of plant-based meat with the animal-based counterparts. Plant-based meat was significantly lower in saturated fat, and protein. However, they were significantly higher in fibre and salt. 40% of meat products were classified as ‘less healthy’. In comparison to that investigators assessed that only 14% of plant-based meat was ‘less healthy’. When saturated fat, sodium, sugar, and overall calorie content were tabulated, plant-based meat products compared favorably to meat. But salt content was often too high in plant-derived foods.

Plant-based burgers were much healthier than conventional beef-burgers, as they contained no cholesterol, less trans-fatty acids and less saturated fat. Vegetable-based food that contains pea protein is particularly valuable with regard to a high protein content.

Criticism of plant-based meat alternatives

At the present time many plant-based meat products have too much sugar and salt in it, but lack iron and vitamin B12. Various authors suggested that the food industry should add iron and vitamin B12 to their products and reduce the sugar and salt content.

Muscle synthesis

Mycoprotein is the active biochemical that builds up the protein of the muscle mass in man. Non-animal-derived dietary protein contains ample amounts of mycoprotein according to this publication. These authors investigated the ingestion of mycoprotein in a dose-response manner. They also measured insulin levels for 4 hours after ingestion of plant-derived mycoprotein. Insulin levels remain higher than normal for a sustained period.

Weight loss

A 2017 study showed that 40 grams of mycoprotein, which is the equivalent of 18 grams of protein was sufficient to lead to a robust muscle synthetic response. 60 g of mycoprotein (27 g protein) provided an optimal response regarding muscle synthesis. Gram for gram milk protein and mycoprotein were equivalent in amino acid bioavailability. Several studies examined weight loss following mycoprotein meals. One study found in overweight patients that chicken protein consumption was  higher in comparison to consumption of plant mycoprotein. The mycoprotein consuming group chose to eat 10% less calories than the chicken control group.

Greenhouse gas emissions and other factors

The publication cited above also included a lot of findings regarding how plant-derived food saves greenhouse gas emissions and other facts. For instance, the pork supply chain requires 3.3-times more fertilizer and 1.6-times more pesticides than the production of plant-derived food. What this means is that plant-derived foods are more environmentally sustainable than animal products.

Plant-Based Meat Alternatives are Healthier

Plant-Based Meat Alternatives are Healthier

Conclusion

Plant-derived foods have improved in the past few decades. Pea-derived plant products are now equivalent in terms of protein content to milk and meat. By eating more plant-derived food people consume less meat, which helps the environment, but also benefits the person who eats it. We know that with the consumption of a certain amount of plant-derived food less people develop cardiovascular disease, diabetes and cancer. 40 grams of mycoprotein, which is the equivalent of 18 grams of protein was sufficient to lead to a robust muscle synthetic response.

Consumer beware

It is important to realize that not all is well with the list of “fake meat” and other highly processed plant-based products. Consumers must read the list of ingredients. If a product contains a laundry list of ingredients that not even an adult can pronounce and understand, it is very likely a highly processed food product that only pretends to be good for you. Should the sodium content be too high, steer away from it. High sugar content means that you put it back in the shelf. All in all, eating more plant-derived foods makes you healthier and improves the environment at the same time. But it is up to us to be discriminating colourful advertising from a nutritionally sound product.

Extreme Heat and Heat Related Deaths

By | Health, heart attack, heat stroke, Mortality

Extreme heat and heat related deaths are closely linked. A record heat wave hit the North West of the US and British Columbia in late June/early July. Many people died from heat stroke and from cardiovascular problems. Here I like to review the medical literature regarding extreme heat and heat related deaths. Also, why is it important to cool down? Much of what I like to communicate was published in a review article by CNN. But I also reviewed many other websites and added links below.

How does global warming contribute to the summer heat?

There are a few explanations how global warming drives the heat in summer even higher.  Essentially, what weather experts are saying is that the jet stream can get stuck in one place during a summer heat wave and the heat keeps getting more intense. Global warming is responsible for heat waves that are higher than in the past. Conversely, in winter global warming can produce cold waves that are colder than in previous years.

Why is extreme heat dangerous for us?

According to the CDC between 2004 and 2018 an average of about 700 Americans died from heat-related causes. The majority of deaths occurred between May and September. There are a number of observations that explain why more people die during a heat wave.

In 2006 there were widespread heat waves and as a result there was a peak in heat related deaths.

  • When people have pre-existing cardiovascular disease, this gets aggravated during a heat wave and the death rate from cardiovascular disease increases during a heat wave. About 25% of heat related deaths are due to an underlying cardiovascular disease.
  • Age by itself plays a big role in heat related deaths. People above the age of 65 are several times more likely to die from a heat related cardiovascular disease than the general population.

     Under reporting of heat related deaths

  • Many times, it is not clear whether a death is due to a medical condition or due to exposure to heat. A death certificate that reports a heart attack as the cause of death during a heat wave will be missed when statisticians attempt to get a number for heat related deaths after a heat wave.

Medical causes why extreme heat and heat related deaths are linked

Our body is used to an inside temperature range between 97 to 99 degrees Fahrenheit (36.1 to 37.2 degrees Celsius). The body can compensate in two ways to counter a rise of the body temperature from heat exposure.

  1. When the brain senses a rise in body temperature, the sweat glands open up and sweat is produced. The evaporating sweat cools down the body temperature.
  2. The body has a second coping mechanism to cool you down. The body can dilate its blood vessels and increase the heart rate. This brings the blood more to the surface. This is when your forehead and the extremities give off heat and you lower your body temperature.
  3. But with exposure to extreme high temperatures both of these mechanisms are not enough to decrease your core temperature.

Avoiding heat-related illness

  • The Mayo Clinic link explains that it is important to drink enough fluids to avoid dehydration. This helps with the second coping mechanism mentioned that cools you down (see above).
  • When the outside temperature rises beyond 86 degrees Fahrenheit (=30 degrees Celsius) it is wise to stay inside air-conditioned premises. This could be your house, if you have air-conditioning, an air-conditioned mall or a public building. A cool pool, bathtub, or cold cloths applied to your arms, legs and torso cool you down as well. Otherwise, intermittent cold showers or cold baths will do the same.

Health conditions that are a higher risk for heat related deaths

The population group at higher risk for developing heat-related illness and eventual deaths are infants and children up to age 4. In addition, anybody older than 65 years is also at risk. Pre-existing medical conditions like diabetes, heart disease and chronic lung disease (COPD) increase the risk of dying from excessive heat exposure. Being overweight or obese is also a risk factor. Heat exhaustion and heat stroke are conditions that require hospitalization.

Common heat-related symptoms

Symptoms of heat exhaustion are: profuse sweating, a pulse that is fast and weak, clammy skin, vomiting and nausea. In addition, there can be cramps in muscles, weakness, tiredness, dizziness, headaches and fainting.

Symptoms of heat stroke are: high fever of 104 degrees Fahrenheit (= 40 degrees Celsius) or higher. Take the temperature with a rectal thermometer to get the core temperature. Other symptoms of heat stroke are altered mental state (confusion, agitation, delirium and seizures). Further, the skin may turn red as the temperature increases, and there may be rapid and shallow breathing. The heartbeat races and the head may throb from a severe headache. Both patients with heat exhaustion and heat stroke need hospital care. Call an ambulance.

Extreme Heat and Heat-Related Deaths

Extreme Heat and Heat Related Deaths

Conclusion

We have to take extreme heat and heat related deaths seriously. Only when we employ counter measures will the death toll from heat related deaths go down. Prevention is everything. But if a person develops heat exhaustion and heat stroke swift transportation to a hospital is a must. This can often save a life. We all need adopt an awareness what our risks are regarding heat and heat related deaths. We need to apply early countermeasures by getting into cooler areas and by drinking enough fluids to prevent dehydration. Prevention is everything regarding extreme heat and heat related deaths.

Melatonin Is More Than a Sleeping Aid

By | Alzheimer’s disease, Anti-aging medicine, Autism, autoimmune disease, Cancer, Cardiovascular disease, Circadian rhythm, Dementia, Diabetes, Health, heart attack, Heart Disease, Hormones, immune system, Inflammation, Insomnia, melatonin, Menopause, mitochondria, Multiple sclerosis, neurological disease, Osteoporosis, Parkinson’s disease, sleep, Stroke

Notably, the January 2021 issue of the Life Extension magazine informs you that melatonin is more than a sleeping aid. It contains an interview between Dr. Roman Rozencwaig and a Life Extension (LE) magazine reporter. It must be remembered that Dr. Rozencwaig dedicated much of his career to the healing effects of melatonin. Another keypoint is that in 1987 Dr. Rozencwaig published a paper together with two other researchers. Specifically, it showed that melatonin production by the pineal gland declines in older age. Markedly, they stated that this is the reason why people age and why diseases of aging develop. Another key point is that Dr. Rozencwaig also stated that taking oral melatonin can promote a healthier life.

Melatonin deficiency causing aging and various illnesses

With the aging process the pineal gland calcifies and melatonin production is steadily declining. Surely, along with this is a deterioration of the circadian hormone rhythm. Meanwhile, the neuroendocrine system in the brain gets disorganized. Accordingly, this causes various diseases to occur. To emphasize, Dr. Rozencwaig says that a proper balance between melatonin and neurotransmitters is what we need to maintain health and longevity. As a result, a daily intake of melatonin supports healthy aging and longevity.

The many clinical effects of melatonin

Oral melatonin tablets help you to fall asleep easier, particularly the population that is older than 60 years.

But besides that, melatonin has many other clinical effects.

  • Melatonin improves immunity, which improves resistance against infections. It helps also in cancer prevention
  • Melatonin maintains the circadian hormone rhythm by synchronizing pituitary and hypothalamic hormone production
  • It protects the brain and may prevent Parkinson’s disease, Alzheimer’s disease, multiple sclerosis, autism, and others
  • Melatonin modulates anti-inflammatory cytokinins in different diseases

Dr. Rozencwaig mentioned that melatonin slows down the aging process. There are multiple intertwining reasons for this. 

Melatonin’s actions against the aging process 

  • Melatonin regulates gene expression. This means that some signs and symptoms of aging can be reversed through genetic switches
  • Because melatonin regulates the immune response, the body is more protected against viral, bacterial and parasitic infections
  • Melatonin helps to overcome chronic inflammation that produces cytokines
  • Melatonin is also liver-protective through stimulation of an enzyme (AMPK). This enzyme regulates cellular metabolism.
  • There are other processes that melatonin is involved in: energy metabolism by protection and restoration of mitochondria.
  • Melatonin protects against osteoporosis by balancing and regulating bone formation versus bone loss.

More actions of melatonin

  • An important function of melatonin is the stimulation of antioxidant enzymes like glutathione peroxidase and superoxide dismutase (SOD)
  • Melatonin regulates sirtuins, which are proteins that maintain cellular health. They protect you from obesity, type 2 diabetes, cancer, heart attacks and strokes, dementia and more
  • As already mentioned, melatonin is a neuroprotective agent and may prevent Alzheimer’s and dementia
  • Melatonin stimulates apoptosis of cancer cells.
  • Oral health and melatonin are related. Melatonin suppresses herpes infections and periodontal disease. Melatonin prevents oral cancers to a certain degree. In addition, dental implants survive better when melatonin is present in saliva.

Prevention of cognitive decline

Dr. Rozencwaig mentioned that melatonin stops much of the cognitive decline of aging. To achieve this the following processes take place.

  1. Melatonin improves the sleeping pattern and increases the amount of REM sleep.
  2. During sleep melatonin removes toxic amyloid and tau proteins. We know that with Alzheimer’s disease these are the proteins that accumulate in the brain.
  3. Melatonin improves myelination of white matter in the brain. This prevents brain atrophy of old age.
  4. The brain is metabolically very active and produces toxic free radicals. But melatonin is a strong antioxidant dealing with free radicals. Melatonin can cross the blood brain barrier and stimulates enzyme production to eliminate toxic reactive oxygen species.
  5. Chronic inflammation also increases with age, but melatonin deals with this condition in the brain.
  6. Here are 3 subtypes of melatonin receptors. The body integrates the multitude of actions of melatonin with the help of these receptors.
Melatonin Is More Than a Sleeping Aid

Melatonin Is More Than a Sleeping Aid

Conclusion

Melatonin is a powerful antioxidant that has many other useful protective qualities as explained. The body integrates various functions like anti-aging, anti-free radical activity, neuroprotection in the brain and more. Melatonin even synchronizes pituitary and hypothalamic hormone production. This helps to integrate the effect of melatonin, which benefits the body in many ways. Melatonin prevents Parkinson’s and Alzheimer’s disease, multiple sclerosis, autism, obesity, type 2 diabetes, cancer, heart attacks, strokes and dementia. Melatonin production deteriorates from the age of about 60 onwards. It is important to supplement with melatonin at nighttime from that age on. Usually, you only need small amounts of melatonin, between 1mg and 3 mg at bedtime. This prevents most of the serious diseases of old age, stimulates your immune system and lets you age gracefully.

The Quality of Food is Important

By | diet, fish oil, food, Health, heart attack, Nutrition, Obesity, omega-3 fatty acids, organic food, osteoarthritis, polyunsaturated oil, Prevention, Processed food, sugar

Many authors wrote books about food; the quality of food is important. Recently I came across a book review regarding the book “The Way We Eat Now” by Bee Wilson. In the March 2020 edition of the health magazine “LifeExtension” Laurie Mathena interviewed Bee Wilson about her book.

Bee Wilson explained that there is a distinct history about the production of food throughout the centuries. She described 5 phases.

  1. During the hunter/gatherer time people were eating a low-fat diet with berries, wild greens and wild animals.
  2. Stage two began around 20,000 BC. It was the agricultural age with a switch to cereals. At that time the population experienced rapid growth.

More stages

  1. Only a couple of centuries ago, agriculture made progress with crop rotation and by adding fertilizers. This led to a more varied diet. People ate more vegetables, less starchy food and animal protein.
  2. After the Second World War there was a major food transition. Processed food was introduced. People started eating more fat, meat, sugar and a lot less fiber. We are now experiencing a phenomenon that we are simultaneously overfed, but undernourished. We get too many calories, but our diet is poor in nutrients. This type of diet causes obesity and degenerative type illnesses.
  3. Stage 5 involves people abandoning junk food and eating more vegetables and fruit again. The more knowledgeable people are about the link between a good diet and health, the healthier people eat. This stage requires governments and other organizations to do their part in assisting people to make that food transition.

Food labeling changes in Chile

Here is one example of how governments can make a difference. This happened in Chile. Chile used to have the highest consumption of sugary beverages in the world. Prior to 2016 the average consumer in Chile bought more than 50% of the food as ultra-processed. This resulted in Chile having the second highest obesity rate after Mexico. The government of Chile decided in 2014 to introduce very simple labels for every food item. The government of Chile demanded that all the foods with too much sugar, high saturated fat, food high in salt and high in calories had proper labels. These labels are simple, hexagonal warning labels.

Warning labels

For instance, if a food product had too much salt in it, it would say in the hexagonal label: “Warning: high in salt”. As the labels had the effect of lowering sales, the food companies reformulated their products very quickly to stay under the threshold triggering the food warning. In 2016 Chile also decided to tax unhealthy foods higher. The government taxed sugar-sweetened colas with an 18% extra tax. Schools had to abandon junk foods sales.

Quality of food

When you start cutting out junk food and other processed foods, the quality of your food intake is improving. Eat more vegetables, and fruit. Eat wild salmon, which provides omega-3 fatty acids. Do not consume vegetable oils like soybean oil, canola oil, safflower oil, corn oil and grape-seed oil. They all contain omega-6 fatty acids. Omega-6 fatty acids are essential fatty acids and they convert mainly into energy. But the problem is that our western diet contains too many omega-6 fatty acids. Omega-6 fatty acids can convert into arachidonic acid, which causes inflammation. This in turn can cause heart attacks and strokes on the one hand and arthritis on the other hand.

The omega-6 to omega-3 ratio is important

In the past a healthy ratio between omega-6 and omega-3 was 4:1 or less. The average American now eats food with 16-times the amount of omega-6 fatty acids than omega-3’s. This is an omega-6 to omega-3 ratio of 16:1. No wonder people get sick with degenerative diseases.

Brain health maintained by eating enough omega-3 fatty acids

Here is a study that looked at brain structure using MRI scans. 3660 participants aged 65 received MRI brain scans. The researchers recorded their food intake with questionnaires. They rescanned 2313 of these individuals 5 years later. The group highest in omega-3 consumption was compared to the group with the lowest omega-3 consumption. Blood tests were also done both initially and 5 years later to verify the omega-3 intake. The researchers found that the higher omega-3 group had less subclinical infarcts and the white matter of the brain was of a better grade. They concluded that fish consumption, the major source of omega-3 fatty acids, had a beneficial effect on brain health later in life, preventing Alzheimer’s disease.

Cook your own food, do not eat out frequently

When you cook your own food, you can choose the right foods as you shop. Stay away from the “dirty dozen”, which is poisoned with insecticides, herbicides or pesticides. Instead you can buy organic foods that have not been sprayed with toxic substances. When you eat out, you have no choice about what you eat. Food in restaurants also contains food preservatives that are not labeled in North America, but that would be labeled in restaurant menus in Europe. In addition, food in restaurants often contains too much salt, too much sugar and the wrong oils. Omega-6 fatty acids are much cheaper than olive oil, and as a result this is what the chef uses.

Transition from stage 4 to stage 5

When you want to transition from stage 4 to stage 5 regarding your food composition you are swimming against the stream of establishment. At this point you are more or less alone when you want to abandon French fries, processed food bars, hamburgers and sugary soft drinks. But the more you eat at home, the more you take out your lunch box with food prepared at home, the more you are winning the war against convenience foods. It is what you put into your mouth, which is the fuel for your body. Don’t compromise regarding the quality of your food!

The Quality of Food is Important

The Quality of Food is Important

Conclusion

The quality of food is important. We have been inundated by ads from the food industry that we should eat fast foods (hamburgers, French fries), processed foods like power bars and drink sugary drinks. We have met the entire lineup on television! But it is best to buy basic foods and prepare all your food from scratch. Be careful that you avoid the “dirty dozen” foods. If you want to eat these, buy the organic food versions. This way you avoid pesticides and other poisons. Stick to extra virgin olive oil as a fat source and avoid vegetable oils. Soybean oil, canola oil, safflower oil, corn oil and grape-seed oil contain a lot of omega-6 fatty oils.

Inflammation caused by vegetable oils

These cause inflammation in your blood vessels and joints. The end result are heart attacks, strokes and arthritis. I also eat a lot of wild salmon and other seafoods, a great source of omega-3 fatty acids. In addition, I take two capsules of molecularly distilled fish oil in the morning and at night. Eat more vegetables and fruit. You are now paying attention to the fact that the quality of food is important.

Clinical Applications of the Fasting Mimicking Diet

By | Alzheimer’s disease, Anti-aging medicine, autoimmune disease, Cardiovascular disease, Diabetes, diet, fasting mimicking diet, food, Health, Hormones, Inflammation, lifestyle, mitochondria, Multiple sclerosis, Prevention, regenerative medicine, stem cells, telomeres, Weight loss

Dr. Kurt Hong, professor of clinical medicine spoke about clinical applications of the fasting mimicking diet in Las Vegas. This was at the 27th Annual World Congress on Anti-Aging Medicine on Dec. 14, 2019. Although he spoke on various forms of fasting, he concluded that the fasting mimicking diet had the best results and was most consumer-friendly.

How we age

Dr. Hong reviewed the processes of aging. We age, because our cells experience oxidative damage and our telomeres (the end caps of our chromosomes) get shorter in time. We also age, because there are genetic mutations in our cells’ DNA and our mitochondria are aging as well. The mitochondria are the small energy packages inside the cells that give us energy. When people age, they have lost mitochondria, there is less energy that the body makes out of food and we feel chronically tired.

Above the age of 65 we are also likely to develop diseases of various organs:

  • Heart disease: 31%
  • Cancer: 24%
  • Chronic lung disease (lower respiratory disease): 21%
  • Alzheimer’s disease: 13%
  • Diabetes: 11%

Women are generally healthier than men and their life expectation is 4 to 5 years longer than that of men.

Cellular and molecular aging

Longevity researchers have done mouse experiments and human clinical trials for decades. Dr. Hong asked the question: how much longer could humans live, if we could cure cancer, heart disease, stroke and diabetes? The answer is: 13 years. But if we transfer the animal data to humans it should be 30 years of longer life. Why is there such a discrepancy? The answer is that it is easy to force good lifestyles onto animals, but humans are resistant to changes. Humans have their habits; they like to continue to smoke and eat fast food instead of switching to a healthier Mediterranean diet. Humans also resist a regular exercise program. And they do not want to hear that they should replace missing hormones with bioidentical ones. The result is that we humans will prolong our lives only by less than 50% of what we could achieve.

The concept of intermittent fasting

Dr. Hong stated, that ten thousand years ago, people did not always have enough food to eat. They were forced to intermittently fast. That did not mean that they had long life expectancies, as there was no cure for any disease. But one fact was true: the body learnt to rejuvenate itself during periods of fasting. And these longevity genes are still present in our genes. But they will only help us when we actually fast for some periods of time.

Dr. Hong reviewed what kind of fasting methods are available.

Prolonged fasting and juice fasting are not among the options. With prolonged fasting electrolyte disturbances become an issue. Juice fasting does not remove enough calories and nutrients. This, however is needed to allow the body to stimulate the longevity genes.

How fasting diets work

Dr. Hong explained that there are essentially 5 fasting diets that are effective in regulating the key nutrient sensitive pathways of IGF-1, TOR and PKA. This increases cellular protection and maintenance. It also increases activation of stress resistance pathways and removes and replaces damaged and dysfunctional cells. Finally, a fasting diet also reduces inflammation, which is often the start of disease.

A review of the 5 fasting diets

Time-restricted eating (TRE)

With TRE the person fasts for 12 to 16 hours every day. The person restricts the daily food consumption to a 4- to 12-hour window. The disadvantage is that this fast is done every day. The period of fasting may not be long enough to change the metabolism, where the above-mentioned effects take place.

Alternate-day fasting  

This is a 24-hour fast every other day with a 1:1 day eating-fasting cycle. This does not appear to be physiological and is disruptive with regard to social activities.

5:2 intermittent fasting

With this fast you fast for 2 days every week. With this 2:5 eating-fasting cycle the person fasts for 2 days every week; the other 5 days you eat as much as you desire.

Although this is effective, it can be quite disruptive to your lifestyle.

Periodic fasting

You fast for 48 to 72 hours every couple of months. This fast is socially more acceptable. It is not that often, just a couple of times in a year. The question remains whether it is effective in changing the metabolism to trigger the effects mentioned above.

Fasting-mimicking diet (FMD)

The original suggestion by Dr. Longo, the inventor of the FMD was that you should fast for 5 days once every month. Since then he has modified it and said that you can achieve similar metabolic changes, if you only fast for 3 days and do this a couple of times per year. I have done the FMD since December 2017 and I adhere to the original schedule of doing the FMD monthly for 5 days. This has provided me with more energy. It is easier to keep my body mass index in the 21.0 to 22.0 range. Dr. Hong explained that the FMD allows you to eat, but it tricks the body into acting like you are fasting. Because you are eating 500 to 600 calories per day, you are getting some fluid and nutrients, so the hunger pangs are tolerable.

More details about the FMD

Here is Dr. Hong’s summary about the FMD: “The stomach sees food, while the cells see fasting”. Dr. Hong said that the FMD is the most user-friendly method of fasting. It also has had the most scientific studies to validate that it is indeed working. Poorly functioning mitochondria and misfolded proteins are removed by a process of phagocytosis. The FMD reduces heart disease, cancer, and neurodegenerative disorders. Stem cell production also gets a boost. This promotes cell regeneration and reduces risk factors of premature aging.

Publication on the effectiveness of the FMD

A publication came out in 2017 reporting about the findings of a clinical trial regarding the FMD.

Researchers followed markers of aging, diabetes, cancer and cardiovascular disease in 100 volunteers. They underwent a FMD for 5 days on 3 consecutive months. The results were astounding. The body mass index, the fasting blood sugar level, triglycerides, total and LDL cholesterol and the CRP were all lower. CRP stands for C-reactive protein, which measures the degree of inflammation in the body. The blood pressure was also lower. Overall the 5-day FMD was a safe method with no side effects. The FMD reduced markers and risk factors of aging and age-related diseases. In doing so it prolongs life by reducing the likelihood of coming down with disease.

Who should abstain from fasting?

Dr. Hong mentioned that the FMD is not for everybody. Pregnant women should refrain from going on it, also type 1 and type 2 insulin dependent diabetics. Anybody who has a sign of an active infection (coughing, having a fever or diarrhea) should be excluded. Other exclusions are people who are underweight (BMI less than 18.5) or are malnourished (protein deficiency). Patients with heart failure and advanced kidney or liver disease should not take part in a fasting program.

Autoimmune diseases and FMD

The myelin sheath around the axon of nerve cells in the central nervous system are supported by oligodendrocytes. In multiple sclerosis (MS) patients T lymphocytes activate macrophages and B cells to produce autoantibodies. They destroy oligodendrocytes breaking down the insulating barrier of the myelin sheath. In MS patients the broken-down myelin sheath suppresses the electrical impulses transmitted through the nerve fibers. The FMD led to clinical improvements.

In a pilot study intermittent fasting changed the gut flora into a healthier flora.

This triggered the immune system in the gut to make less inflammatory T cells producing the IL-17 cytokines. There was also an increase in regulatory T helper cells.

Inflammatory bowel disease (IBM) can be improved with several courses of FMD. As the authors showed, intestinal inflammation improved with FMD. The intestinal gut flora improved with the FMD and it promoted intestinal regeneration.

Reversal of physical and functional decline

The fasting mimicking diet (FMD) has a variety of effects on the human body. Dr. Hong showed a slide where we could see that ketone bodies, cortisol and ghrelin levels are increased in the blood. At the same time glucose, insulin, leptin and IGF-1 levels are reduced. In addition, triglycerides and LDL levels are getting lower. Inflammatory markers including the C-reactive protein (CRP) are reduced as well.

Effects of the FMD on various organs in the body

A look at all of the organs shows that in the liver the ketone body production and insulin sensitivity are up. Glycogen production in the liver as well as the liver size are down.

The intestines produce ketone bodies. In the skeletal muscles the insulin sensitivity is increased, while the muscle structure and function are improved. In the brain the hunger feeling increases the release of neurotropic factors including the neuropeptide Y. Cognitive function and stress resistance increase with the FMD. The FMD reduces inflammation and oxidative stress in the brain. With respect to the cardiovascular system the heart rate drops down and blood pressure gets lower. The insulin production in the pancreas is reduced.

Fatty tissue

In fatty tissue lipolysis is up and also the production of adiponectin. This is a protein hormone involved in glucose and fatty acid metabolism. Insulin sensitivity with the FMD is also increased. On the other hand, the FMD reduces fat mass, leptin production and inflammation.

The FMD is the solution to preventing disease and prolonging your life

All of these effects lead to a reversal of physiologic and functional declines. Age-related metabolic diseases like type 2 diabetes are postponed or eliminated. The FMD prevents neuro-cognitive decline like Alzheimer’s disease. In addition, the risk of developing cancer is getting lower. In summary, the FMD improves the health-span, quality of life and can prepare you for a long life.

Clinical Applications of the Fasting Mimicking Diet

Clinical Applications of the Fasting Mimicking Diet

Conclusion

Dr. Kurt Hong is a professor of clinical medicine at UCLA. He gave a talk at the 27th Annual World Congress on Anti-Aging Medicine in Las Vegas on Dec. 14, 2019. He discussed what we could do to help patients with various autoimmune diseases like multiple sclerosis, rheumatoid arthritis and inflammatory bowel disease. It turns out that the fasting mimicking diet (FMD) is the best solution to reduce inflammation and modify  the autoimmune response from aggressive T lymphocytes. With the FMD you consume only 500 to 600 calories per day for 5 days every month. The rest of the days of the month you eat a healthy Mediterranean-type diet.

Fasting mimicking diet, the best way to treat autoimmune diseases

Dr. Hong explained in detail what cellular mechanisms are at work to achieve the modification of the immune system in autoimmune diseases. The FMD is also the solution to slow down aging in healthy people. Dr. Hong discussed clinical applications of the fasting mimicking diet fort autoimmune diseases. It is easier to prevent disease than it is to cure an illness. The FMD is an easier way, because you don’t fast completely, you only reduce your food intake to the bare minimum, but your body “thinks” that you are fasting.

Ultimately, this approach does take some effort, and it does take time to familiarize yourself with it. If patients do it for the first time, they will experience some hunger, the first and second day tend to be a hurdle! Once you make it part of a health routine on a regular basis, it is a lot easier.
